There are several problems that occur when using IMEI, IMSI... that are described here:

The recommended approach is to use:

http://developer.android.com/reference/android/provider/Settings.Secure.html#ANDROID_ID

String unique_id = android.provider.Settings.Secure.getString(getContentResolver(), android.provider.Settings.Secure.ANDROID_ID);

Answer 2

check IMEI.
